The detonation velocity values presented here are typically for the highest practical density which maximizes achievable detonation velocity. [1] The velocity of detonation is an important indicator for overall energy and power of detonation, and in particular for the brisance or shattering effect of an explosive which is due to the detonation ...
Detonation velocity can be measured by the Dautriche method. In essence, this method relies on the time lag between the initiation of two ends of a detonating fuse of a known detonation velocity, inserted radially at two points into the explosive charge at a known distance apart. When the explosive charge is detonated, it triggers one end of ...
As a simple approximate equation, the physical value of is usually very close to 1/3 of the detonation velocity of the explosive material for standard explosives. [1] For a typical set of military explosives, the value of D 2 E {\displaystyle {\frac {D}{\sqrt {2E}}}} ranges from between 2.32 for Tritonal and 3.16 for PAX-29n.
The velocity of detonation in solid and liquid explosives is much higher than that in gaseous ones, which allows the wave system to be observed with greater detail (higher resolution). A very wide variety of fuels may occur as gases (e.g. hydrogen ), droplet fogs, or dust suspensions.
Astrolite A, a secondary (and less common) type of Astrolite, is sensitized by the addition of finely powdered aluminium to the Astrolite G mixture. Though it has a lower detonation velocity (approximately 7,600 m/s) than Astrolite G, the addition of the aluminium increases both its density and explosive brisance, moderately increasing its overall effectiveness/RE Factor.
Detonation can be initiated only by a shockwave, such as when a detonator inserted into it is fired. [8] When detonated, C-4 rapidly decomposes to release nitrogen, water and carbon oxides as well as other gases. [8] The detonation proceeds at an explosive velocity of 8,092 m/s (26,550 ft/s). [14]
The velocity of detonation is about 7600 m/s (25,000 feet per second). Composition C-3 consists of 77%–85% cyclonite ( RDX ) and 15%–23% gel made out of liquid nitro compounds (e.g. liquid DNT and small amount of NT ) and nitrocellulose or butyl phthalate and nitrocellulose.
It states that the detonation propagates at a velocity at which the reacting gases just reach sonic velocity (in the frame of the leading shock wave) as the reaction ceases. [1] [2] David Chapman [3] and Émile Jouguet [4] originally (c. 1900) stated the condition for an infinitesimally thin detonation.
